A few days ago, Britain's former spy chief warned his country is going through a political nervous breakdown. The leak of confidential memos by Britain's ambassador to Washington about the Trump administration only seems to make that official.

Thanks to the disclosure of two years' worth of cables by diplomat Kim Darroch, U.S. President Donald Trump now knows that however thick the British laid it on during his state visit to London last month, one of their most senior and respected diplomats views his administration as "uniquely dysfunctional" and "inept."

That's awkward. It's one thing to get an earful from your enemies. Even the thin-skinned Trump usually brushes those off with a clipped "fake news" dismissal. But it's quite another to hear what your supposed friends say about you when they think you aren't listening. Little wonder Trump sounded peeved when he said that Darroch "hasn't served the U.K. well."
